I have not installed my Fizzle yet, but my question is on the back side, that has two holes, is there room that a third hole and hose would clear if located at the back bottom? The reason I ask is if the smaller outlet hole was located at the bottom edge of the back side instead of above the middle main outlet, you could run it to a low mounted pisser, and the IC would be self draining that way. No winterizing required.
That is how I ran the outlet line on my GPR jetworks kit, out the bottom of the exhaust pipe to a low pump tunnel mounted pisser. Self draining.
